IMPROVED COMPOSITION OF MATTER.

Specification forming part of Letters Patent No. 55,951, dated June 26, 1866.

To all whom it may concern:

Be it known that I, LEWIS FRANCIS, of the city, county, and State of New York, have invented, made, and applied to use a new and useful composition of matter for various purposes where elasticity is required-for the linin g of vessels, for forming irinters" ers, for the formation of images, "mo s,and for casting into plates from which impressions may be taken, of which the following is a specification.

The nature of my invention consists in combining glue, glycerine, and silicates, either with or without saccharine matter, to form a new and useful composition of matter for the above purposes.

To enable those skilled in the arts to make and use my invention, I will proceed to describe the same.

In making my improved composition the ingredients are employed in about the following proportions: lue four (4) pounds r \icerine. four (4) d'flflils; silicates fobr aboutfive (5) or ten (10) minutes. The wa er is then decanted and the glue is left to stand about four (4) hours to soften. The glue is then placed in a steam or glue kettle and heated, when the glycerine is added. Next add the silicates employed and (when used) the saccharine matter. The illlgllfii fifllelllflflfi to boilat about 200 Fah'feiilieiti' rforty (40) cakes of any desired form. ca es are c osed to the air several days, in

kaolin tite luuid waterlass u ersearti 'c., or anyo t ecompounds o'i s1 lCLOlH- uniina as um 8.70. Y e s1 ica es to e used have not been treated by their proper solvents to make them in the form of liquid quartz, care must be taken to have them properly pulverized or obtained by precipitation in the form of kaolin, &c.

The proportions in which the ingredients are employed may be greatly varied, as, if a compositionharder than that first described be required, the ingredients may be employed in these proportions, namely: lue four (4) pounds; glycerine, two (2) poun ssilicates four (4)poum s; saccharine matter (wl'ien' used,) four (4) pounds. Ur WIPE en 1e composition is required softer the ingredients may be incorporated thus: 'lue four (4) pounds-, glycerine eight (8) poun ssilicates four pounilssaccharine matter (when used,) two POUW Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Combining glue, glycerine, and silicates, with or without saccharine matter, to form a order that a w e ng in the composition may be tfioroughlv eva orated or a vacuum-pan may be employed for the purpose. By this last process all liability of the composition to shrink from the presence of water is obviated. The composition is then ready for new and useful composition of matter for various purposes.

LEWIS FRANCIS.
